Specification of Letters Patent. Patented Aug, 27 1912,

Application filed February 27, 191-1. v Serial No. 611,065.

Tooll'w'h'om it may concern:

Be itknownthat 1, JOHN M. C. Jones, a citizen of the United States,residing at Gibson City, .in the county of Ford and State of Illinois,have invented certain new and useful Improvements in Green-Corn-vCutting Machines, of which the following is a specification, referencebeing had to the i accompanying drawings.

Another object is to provide anew and im Y proved means for feeding theears to; the cutting knives one after another as fast as the machine canhandle them.

Another object is to improve the con. struction and operation ofmachines of this general type in sundry details hereinafter pointed out.

The means by which I have accomplished these objects are illustrated inthe drawings and hereinafter specifically described.

That which I believe to be new is set forth in the claims.

In the drawings :F1gure 1 1s a front elevation of one end of themachine. Fig. 2

is an end view ofthe parts shown in Fig.

' I seen fromthe right in said figure. Fig. 3

is a section taken on line ,33 of Fig. 1. Fig. 4 is an end view of themachine seen from the left in Fig. 1. Fig. 5 is substantially a sectiontaken on line 5--5 of Fig. 1. Fig. 6' is substantially a'section takenonline 6+-6 of Fig. 5. Fig. 7 is an end view of a portion of the machinewith the feeding rolls and connected parts removed, showing the partsbywhich "the ears of-corn are received from the feed? ing rolls. Fig. 8 isa fragmentary view showing the manner of mounting the shafts which'carry the spurs which .control the ears in theirprogress from thehorizontal to the vertical cutting knives. Fig. 9 is a top view of theparts shown in- Fig. '8. Fig. 10 is afragmentary view showing themounting of two of the diagonallyextending shafts which carry the spurrollers which forward the cobs after theprincipal part of the oorn hasbeen cut from them, and showing also the mounting of the scrapers whichcooperate therewith. Fig.- v1 1 is a view diagonally downward at theparts shown in Fig. 10. Fig. 12 is a fragmen-- tary elevation of thelower end of one of the pivoted boxes in which are mounted the spurroller shafts above referred to. Fig.- 13 is a view diagonally downwardupon one of the upper scrapers. Fig. 14. is a side ylew of the scrapershown in Fig. 13, showmg the cooperating lower scraper also inconnection therewith. Fig. 15 is a top or plan view of the end ofthe-lower scraper .as shown in Fig. 14. Fig. 16 is a section perspectiveview of the upper horizontal cutting knife and .arm. F ig.'18 is aperspective view of the upper horizontal cutting knife removed from itsarm. Fig. 19 is afiperspective view of the lower horizontal cuttingknife and arm. Fig. 20 is a side view of the two vertical cutters andthe spring by which they are held in proper relation to each other. Fig.21 is a view on line 2121 of Fig. 20'. Fig. 22 is a top View of thespring shown in Fig. 20. Fig. 23 is a perspective view of the lower endof one of the verticalcutters'. Fig. 24 is a rear elevation of thepartof the machine by which the corn is delivered to the cutting andscraping tools.

The scrapers 157 to 159are caused to rise positively with said shaft-boxes by means 0 setscrews 165 car: ried in the upper ends of arms 166 rising from saidscrapers and bearing at their lower ends on said shaft-boxes, as best-,45 shown in Fig. 3. 1 Y Each of the scrapers158-160 is provided at itsrear end with a T-shaped he'ads167; (see Fig. 15).

to rise against the action of the spring 108,

and the tongues126-127 serving to kee the cob in proper alinement. Asthe lea ing end of the cob leaves the spur wheels l0-111, it immediatelyengages the blades 122 and 123 which strip from the. cob practically allthe remaining corn,'tlie blades 122-123 being vfree to give sidewiseagainst the force of the spring 119 but being kept substantiallycentered by the block 121.

The cob is then caught by the first pair of i the upper roller beingfree to give upward,

as will be readily understood, against the action of the spring 142. Asthe roller 140 is forced upward, the scraper 1157 is lifted with it byreason of the set-screw 165 hearing on the uppersurface of the box-130,

the set-screw 165 being regulated to suit the average size of the cobsof the corn be roller 141 against the action of the spring 169, ifnecessary, the cob being forced between the scrapers by the spur rollersen-' gaging it. The scrapers are beveled (see Fig. 16) at theiroperativeportions in order to make it possible to force the cob between themalthough they are, held normally by spring pressure too close togetherto permit of thepassage of the cob. As the leading end of the cob leavesthe scrapers 157-158, it is caught by the next succeeding 'pair of spurrollers 138 139 set at substantially right angles to the positions I ofthe spur rollers and scrapers between which it has-just passed; Eachsucceeding pair' of spur rollers and scrapers act precisely as dothe'first set. By reason of the rollers being set at an angle to eachother,

eachpair of rollers corrects any slight departure from exact centralalinement which the cob may have been permitted to assume by thepreceding pair. Furthermore, by reason of having the roller shaftsset'vat'an angle and driven from two independent shafts instead of byasingle shaft, I am enabled to place the rollers very much closertogether in the line of-progress of the cob. The result is that the cobis controlled much more positively in its progress, and a much shortercob can be run through the machine Without danger of its being deflectedfrom the proper path than has ever heretofore been successfully sentthrough a machine of this class. Moreover, there is another feature ofthe construction of my.-'machine which assists to this same endf-namely,the fixing of the lower spur rollers in permanentfixed position, theupper spur -the front end of the-shaft 52 roller only being free to giveto suit the size of the cob. This has. a distincttendency to keep thepath of-the cob-through the machine in an exact straight line andprevents the cob being forced through in a ing the corn away from themachine. The

cobs, after being scraped by the successive pairs of scrapers, aredelivered through the opening 178 and out of the machine.

come jammed between the spur rollers or. the scrapers, a movement of thelever 146 to its uppermost position. loosens the springs. 142, making itcomparatively easy to remove the cob from between the parts. After thesprings 142 have been properly vregulated bv the movement of the lever146,and before such lever has been moved upward to loosen the springs asjust described,-the pin 155 is designed to be placed in the opening. 154corresponding to the position of the lever, so that when it v is desiredagain to-tighten the springs 142 it is-only necessary to pull the leverdown into contact with the pin 155 when the springs will be againtightened to the same tension as that before the lever was moved upwardto loosen the springs.
